DORYPHORA VIGINTIPLAGIATA, Sp. IIOV. 



Black, above flavous, head and the disc of the thorax greenish 

 black, the latter extremely minutely punctured ; elytra strongly 

 and semiregularly punctured, each elytron with ten obscure seneous 

 elongate spots (4, 3, 3) placed transversely below the base and 

 below the middle. 



Length 12 millim. 



Oblong, the greatest convexity placed at the middle of the 

 elytra ; the head sparingly and finely pvinctured, with a small 

 flavous spot at the vertex ; antenna? nearly extending to the base 

 of the thorax, black, the lower four joints flavous below, terminal 

 joints distinctly widened ; thorax more than twice as broad as 

 long, the sides rounded anteriorly, the angles acutely pointed, the 

 surface flattened at the sides, exceedingly finely and closely 

 punctured ; the disc, in shape of a large transverse patch, greenish 

 black, the anterior and lateral edges of the patch sinuate, the 

 rest of the surface flavous ; scutellum black ; elytra closely and 

 strongly punctured in ii-regular rows, which are slightly ariunged 

 in pairs near the suture, flavous, with ten elongate blackish-feneous 

 spots arranged in three transverse rows, one below the base 

 consisting of four spots, of which one occupies the shoulders, the 

 second row below the middle composed of three spots, the outer 

 one of which is strongly transverse in shape, and the third row of 

 three small spots near the apex. 



Hah. Espirito Santo, Brazil. (A single specimen.) 



This species might easily be mistaken for D. fasciato-maculata 

 St., which it resembles almost entirely in coloration and pattern, 

 but is much larger, the thorax is much more transverse and is 

 devoid of the small spot placed at each side of the larger patch as 

 in the above-named species, the elytra have the punctation less 

 regularly and less distinctly geminate. In all specimens of D. 

 fasciato-macidata I have seen the thoracic central patch extends 

 quite to the anterior margin ; in the present insect the latter is 

 flavous like the sides, in both species the suture is narrowly 

 seneous as Avell. 



DoRYPHORA LATERALIS, Sp. nov. 



Olivaceous green, more or less stained with testaceous below, 

 antemife entirely testaceous ; thorax very minutely and sparingly 

 punctured ; elytra strongly punctate-striate, the extreme basal 

 margin and a sutural stripe dark fulvous, the ninth interstice 

 obscure flavous. 



Length 15 millim. 



Subglobular, deflexed posteriorly, the head impunctate, the 

 labrum testaceous ; antennee slender, the terminal joints scarcely 

 thickened, entirely testaceous ; thorax twice and a half broader 

 than long, the sides straight at the base, rounded anteriorly, the 

 anterior angles broad and produced but not mucronate, the disc 

 convex, dull green, subopaque, with some minute punctures, the
